Kinetic Energy = ½mv2

(m=mass v=velocity)

Mechanical Energy = PE + KE

(PE= potential energy KE= kinetic energy)

Next to or underneath your graph answer the following prompt.

•Using your averages describe the outcome of your PACE experiment.

•In one or more of the trials was there a time where the data seems off or inconsistent. Circle it, or star it.

•What might have happened during that event? Explain.
